just to add something hear. i've got a gt3076 .82 on the way atm, through MTQ. they assured me it was the proper version but after talking to the performance guy there it seams its a cropped 54mm turbine wheel. he insisted garret must measure in a different place to him and thats why its different....

next time i take the 33 out i will get a pic of the hand controller showing boost and revs.

its a 25

same manifold as Als

3582r-iw .82

ive seen 5 psi by 2600rpm on a big hill, and i reckon im around the 4k mark for 24 psi.

i will pay attention and get a pic for you.

Going up a hill is putting a big load on the engine, thus resulting in a faster spool rate. How is it on a flat road?

Hey Al, It looks like your using a ETM Manifold........ What are your experiences

with this manifold?

Custom made or of the shelf ETM?

Manifold is top notch and am very happy, took a little long to receive though. Just told him my specs (rb25 head, rb30 bottom end, GT30r-IW, R33 GTST) and he did the rest. No issues with fitment or clearance, even my mechanic was impressed with quality and price.

What ever you do, do not buy his high capacity sumps; completely different scenario. Felt like driving to his w/shop (from Melb) and shoving it up his A$$, complete waste of time and stress, delayed my build by over 3 months.

An sr20 turbo will have a smaller rear housing, so it may spool a little faster, even though the engine is only a 4cyl.

I wouldn't believe anyone that claims they achieved 19psi by 3800rpm, on a mild rb25, using that turbo.

Fixed check my thread here

3900 full boost close enough for you?

Do you believe now?

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
